Frost dates are never 100% accurate, given that they are the average of several years of dates and will always be an approximation. However, with climate change in the mix, it’s increasingly difficult to nail down a particular date and call it the average last frost.
So, how do we deal with that? Well, the best method is to simply view the frost dates as an approximation and a rough guideline, while also paying close attention to weather forecasts and, honestly, going with your gut! If you feel it will be warmer sooner than what the frost date would suggest, then plant sooner—but also be prepared to protect your crops in case a surprise frost does hit.
